With the entry of 3G and WiMAX players, the Indian mobile subscriber base is expected to reach 1110 million by the end of 2015. To meet mobile infrastructure demand, India will require approximately 350,000 to 400,000 mobile telecommunications towers in the next 7 to 8 years. Presently only 40% of mobile telecommunications towers are shared in India. The high growth of subscribers and initial cost of mobile telecommunications towers and license conditions will force mobile network operators to share infrastructure with other mobile network operators, specifically with new operators. The Indian government has allowed sharing of passive and active components of mobile telecommunication infrastructure. With the changing demand of the telecommunications infrastructure, many new telecommunications tower business entities and companies and mobile telecommunications tower business models are being explored. In this paper, the author presents the landscape of the mobile telecommunications tower industry in India, which consists of four types of companies and trends with respect to the strategies of telecommunication tower companies, especially tenancy ratio. Emerging features of the mobile telecommunication towers industry in India are also presented.

The increase in the number of cases of failure of information and telecommunication networks due to cyber attacks determines the need to protect them from this type of attacks. The issue of increasing cyber security in the conditions of conducting operations by groups of troops (forces) is very important. Due to the armed conflict in the East of Ukraine, the military-political instability in the Middle East, the struggle for influence on world financial and energy flows, the global military-political instability is intensifying. This is due to an increase in the number of communication devices in information and telecommunication networks, as well as an increase in the number of possible attacks that can be used to disrupt the operation of an information and telecommunication network. Considering the above, the object of research is a special purpose information and telecommunication system. The subject of research is cyber security of a special purpose information and telecommunication system. Classical methods of scientific knowledge, namely analysis and synthesis, were used during the research. The research identifies factors that affect cyber security in a special purpose information and telecommunications system. All this must be taken into account while planning and deploying a special purpose information and telecommunication system. The analysis of the consequences of the impact on the information and telecommunications system of special purpose of modern devices of defeat and the impact of devices of radio-electronic suppression and other factors was carried out. A typical special purpose information and telecommunication system does not fully meet the requirements for constant readiness to ensure the management of troops (forces), stability, mobility and throughput. A formalized description of the task of improving cyber security in a special purpose information and telecommunications network is provided. The components that affect the level of cyber security of the special purpose information and telecommunication network during the group's operations have been established. The impact of the specified conditions and factors must be reflected: in the planning documents during the planning of the deployment and operation of the group's information and telecommunications system; in the software, during operational management.

This paper empirically studies the impact of telecommunications infrastructure construction on economic and social innovative development using panel data from 31 provinces in China spanning from 2009 to 2022. The research findings indicate that telecommunication infrastructure significantly promotes innovation in terms of R&D investment, knowledge output, and application output. In addition, at various stages of telecommunication technology development, the impact on innovative development varies. Iterative updates in telecommunication technology drive higher R&D expenditures, facilitating better utilization of innovation outcomes in industries. Moreover, there are regional disparities in the influence of telecommunications infrastructure on economic and social innovative development. In the eastern regions, telecommunications infrastructure construction primarily promotes mobile communication, with clear spillover effects. In contrast, in western regions, it mainly facilitates fixed communication networks. Thus, further strengthening telecommunications infrastructure construction provides a new impetus for social innovative development and long-term sustainability. It is essential to persistently advance the coordinated construction of mobile and fixed communication infrastructure to achieve regional development coordination.

The development of information and communication technologies has contributed to the fact that the telecommunication industry has become one of the strategic sectors of the economy on which the functioning of other branches of the economy depends. Therefore, the objective of the study was to determine the factors that influence the competitiveness of telecommunications companies and shape the image of the future telecommunication sector as a whole. The article analyzes two theoretical approaches to the definition of competitiveness: static and dynamic. Due to the importance of the dynamic approach for determining the competitiveness for the telecommunication market, the main internal and external factors affecting telecommunication companies nowadays and having a significant effect in future were identified. External factors were determined using STEEPV-analysis. For internal factors, the following classification was proposed: technological, organizational and marketing innovations. Among the external factors, the digitalization of the economy and society becomes the most important for telecommunication companies, technological innovations are among the internal factors. The factors revealed during the research can be used for foresight of the telecommunications sector of Russia, the definition of scenario conditions for forecasting the development of information and communication technologies, the formation of a strategic policy of telecommunication companies.

The Nigerian Telecommunications Industry is classified as the fastest-growing and most competitive Telecommunications industry in the world. It has the largest subscriber base in Africa with over 150 million subscribers. Due to the increased competitiveness in the telecommunication industry in Nigeria, customer retention has become the focus of telecommunication providers. It is in this light that this paper is built. Hence, the general objective of the paper is to determine the effect of experience marketing on customer retention in the Nigerian Telecommunications industry. The study made use of primary data gotten through a validated set of structured questionnaires which was distributed to a selected sample of 402 respondents within the six states of the south-south geo-political zone of the Niger Delta Area of Nigeria, which are Akwa-Ibom, Bayelsa, Calabar, Edo, Delta and River States. The paper adopted correlation and regression analysis to test the formulated research questions and hypotheses. After the analysis, it was discovered that there was a strong and positive effect of experience marketing on customer retention in the Nigerian Telecommunications industry. The study, therefore, concluded that Customer Service Quality, Customer Brand Relationship, and Customer Emotional Experience are good indicators and dimensions of Experience Marketing that could increase the degree to which customer retention is enhanced in Telecommunication Firms in Nigeria. Hence, it was recommended, among others, that Telecommunication operators in Nigeria must switch from the traditional marketing approach to an experience-based marketing strategy if they want to remain relevant and competitive in the globalised telecommunication industry.

Intense competition in the global telecommunications field has resulted in heavy investments ininnovative approaches to remain competitive. Kenya has followed this global trend following theliberalization of market operations. This article highlights how innovation strategies influence thecompetitive advantage of telecommunication companies in Kenya. Specifically, the study’s objectiveswere based on how product innovation, process innovation, technological innovation, and marketinnovation influence the competitive advantage of telecommunication companies in Kenya. The studyused a descriptive design to sample 26 licensed telecommunications targeting 311 management staff.The proportionate sampling yielded 247 responses. Using linear regression analysis run through theSPSS computer program, the results show that innovation strategies statistically influence thecompetitive advantage of telecommunication companies in Kenya with a beta of .376 (β = .376t = 6.613,p<.05). The study concludes that innovation strategies, if well harnessed, provide a platform forachieving competitive advantage over the long term. Innovation theories are truly supportive of thedynamic application of innovation strategies within telecommunication companies actively seizing anysuch opportunities in the short term. Undeniably, translation into competitive advantage will dependon the aggressiveness of each individual company. The study recommends that firms should create andmaintain special teams to lead implementation of innovative strategies in order to attain competitiveadvantage in the telecommunications sector.

Purpose – The purpose of this paper is to investigate the long-run impact of telecommunications revenue and telecommunications investment on economic growth of Ghana for the time horizon 1976-2007. Design/methodology/approach – The paper uses the Augmented Dickey Fuller and Phillips Perron unit root test to explore the stationarity property of the variables and the Engle-Granger residual-based test of cointegration to model an appropriate restricted error correction model. Findings – The outcome of the analysis produced mixed results. Telecommunications revenue does not contribute significantly whilst telecommunications investment does. Practical implications – Policy makers will have to deal with a conundrum; while designing targeted policies that will attract more telecommunication investment in order to maximize the corresponding revenues and the economic growth it brings in its wake, they must at the same time find ways and resources to grow the economy to a point or threshold where revenue from telecommunications can have the much needed impact on their economies. Originality/value – The study is one of the first that has investigated the line of causality between telecommunication revenue and economic growth unlike previous research that mainly focused on the impact of telecommunication infrastructure on economic development.

Telecommunications has gained in importance in the world economy. Regulation of this industry therefore has become a crucial policy issue of the governments around the world. In the thesis, I examine regulation of telecommunications services in OECD countries. Special attention is given to the New Zealand regulatory regimes before and after the second regulatory reform. As the first regulatory reform in telecommunications in New Zealand occurred over a decade ago, regulatory measures had to be adjusted to suit the current environment. This was the main reason for the establishment of a government-mandated inquiry. Measures were sought and evaluated to reduce or eliminate problems that were associated with the old regime, especially the not-very productive commercial negotiations and the not-very-efficient process and the institution that operators relied on for solving their disputes. I use Coase Theorem to examine why commercial negotiations did not work as effectively as the government envisaged. With the adjustments of regulatory institutions and their functions, the government wishes to counter the time-consuming dispute resolution process that works against new entrants, and to increase the incentive to negotiate. The second regulatory reform shifted the regulatory burden from the courts to the industry and the Commerce Commission. Comparisons of the two regimes are made to analyse the differences of the two regimes to achieve better understanding of the social and economic goals of the New Zealand government. The two regimes are evaluated to provide information on the potential problems that might emerge in the future. Topics such as the difficulties a regulator faces in imposing appropriate regulatory measures, the direct relationships of regulation and competition and the indirect relationships of regulation and telecommunications performance are analysed in depth.

In the two years 1989-1991 the environment of Poland's telecommunications was fundamentally transformed. This dissertation is an exploratory case study addressing four principal aspects of that country's changing telecommunications: (1) telecommunication regime or the structure of rules in which telecommunication systems function; (2) telecommunication services, defined as the means and methods of communicating from a distance by processing and relaying an electro-magnetic signal (categorized into telephone, mobile, data-messaging, information, data-carrier, and entertainment); (3) telecommunication equipment, or markets for switching, transmission and terminal equipment; and (4) telecommunication subscribers, or principal characteristics of the customer-base in the residential, professional, rural and urban market segments. Each aspect is examined for the purpose of capturing the on-going change. The dissertation identifies the principal agents of change and maps the new conditions onto the models developed by Cowhey and Aronson. Institutional pluralism, market competition, shortage alleviation and market restructuring have transformed Poland's telecommunication environment from the scarcity model to a version of the boutique model.

Resumo:

Over the last decade, both the Internet and mobile telephony has become parts of daily life, changing the ways we communicate and search for information. These two distinct tools are now slowly merging. The topic of this thesis is TCP over wireless, and the automatic control that is used both within the system, from the link-layer power control to the end-to-end congestion control. It consists of three main contributions.

The first contribution is a proposed split-connection scheme for downloads to a mobile terminal. A wireless mobile terminal requests a file or a web page from a proxy, which in turn requests the data from a server on the Internet. During the file transfer, the radio network controller (RNC) sends radio network feedback (RNF) messages to the proxy. These messages include information about bandwidth changes over the radio channel, and the current RNC queue length. A novel control mechanism in the proxy uses this information to adjust the sending rate. The stability and convergence speed of the proxy controller is analyzed theoretically. The performance of the proposed controller is compared to end-to-end TCP Reno, using ns-2 simulations of realistic use cases. It is shown that the proxy control is able to reduce the response time experienced by users, and increase the utilization of the radio channel. The changes are loalized to the RNC and the proxy; no changes are required to the TCP implementation in terminal or server.

The second contribution is the analysis of an uplink channel using power control and link-layer retransmissions. To be able to design the link-layer mechanisms in a systematic way, good models for the link-layer processes, and their interaction with TCP, are essential.The use of link-layer retransmissions transforms a link with constant delay and random losses into a link with random delay and almost no losses. As seen from the TCP end points, the difference between such a link and a wired one is no longer the loss rate, but the packet delay distribution. Models for the power control and link-layer retransmissions on the link are used to derive packet delay distribution, and its impact on TCP performance is investigated.

The final contribution considers ways to optimize the link-layer processes. The main result is that TCP performance, over a wireless link with random retransmission delays, can be improved by adding carefully chosen artificial delays to certain packets. The artificial delays are optimized off-line and applied on-line. The additional delay that is applied to a packet depends only on the retransmission delay experienced by that same packet, and this information is available locally at the link.

Several factors affect the development of telecommunications policy in a country. These include government intervention, geography, alliances, and economic stability. By studying different countries, and comparing these factors and the rates of growth of each state, one can further understand the different levels of telecommunications development. This thesis will explore telecommunications policy, its success and failures, in the Dominican Republic and Haiti, where telecommunications has become a major source of jobs and economy due to foreign investments. Analysis of telecommunications policies, regulatory bodies, and agreements will be studied and compared to each country's rate of growth in the past 10 years. This thesis will provide recommendations for the successful implementation of regulatory policies in the named developing Caribbean nations. By examining the policies in these nations, this thesis will determine the effectiveness of the country's telecommunications policy. Additionally, the thesis will explore the influence of specific actors, such as corruption, nonenforcement of regulatory laws, lack of developed accounting and auditing systems, and the limitation of the government in developing policy.

The key word for the thesis is long-term demand forecasting which have been applied on telecommunications and especially on broadband accesses and traffic.

The objective with the thesis has been to structure and present work on long-term broadband forecasting, to evaluate the forecasting results and to extract the learning. Each main chapter ends with a section called experiences and conclusions.

The thesis is organized in seven main parts.

The first part addresses application of the Delphi technique for long term forecasting broadband accesses. Three Delphi surveys, which have been conducted during a long period, have been evaluated. All three Delphi surveys have used similar procedures in carrying out the survey, except that two of the Delphi surveys were postal surveys, while one was carried out on site. The applied procedure is evaluated based on an important reference article on Delphi surveys and also based on the long-term forecasting results. The Delphi surveys are not very often used. Hence, the description of the way to conduct the surveys and the experiences and also the evaluations of the results are given specific attention in the thesis.

The second part of the thesis has the title “Long-term broadband technology forecasting”. Results from three papers are presented and evaluated. The papers show the evolution of the forecasting modelling. The first forecasts for the broadband evolution in Western Europe were made before broadband was introduced in the residential market in Western Europe. The long-term forecasts were developed based on Logistic models. The modelling also includes substitution effects between broadband technologies. Experiences have shown that technological knowledge and techno-economic evaluations are crucial for making long-term broadband forecasts. Some attention is also put on available broadband accesses statistics and an approach to separate aggregated broadband statistics to access statistics for the business market and for the residential market.

“Long-term forecasting models for cost components and technologies” is the third part in the thesis. To be able to evaluate broadband technologies, techno-economic calculations of the “economic” value of the relevant broadband technologies are very important. The extended learning curve model invented by Borgar T Olsen and Kjell Stordahl is presented. The model is much more powerful than the simple exponential learning curve. The extended learning curve makes long-term forecasts of component costs and has the ability to be used directly on technoeconomic calculations, as opposed to the traditional learning curve model, which does not predict the cost as a function of time. In addition the extended learning curve model has interpretable parameters. It is shown that the model may utilize a priori information in cases where too few observations are available.

The fourth part addresses long-term traffic forecasting. Three papers are enclosed. The chapter starts with a short overview of relevant forecasting models. Then attention is paid to forecasting and network planning. A comprehensive overview of the field is given together with numerous references in the enclosed paper “Forecasting – an important factor for network planning”. Longterm forecasts for the core network is analyzed and discussed. Also some figures for the total broadband traffic evolution in the Norwegian core network is presented.

The last paper described in the chapter shows how long-term traffic forecasts on aggregated level can be used for traffic matrix forecasting by using the extended weighted least square method. The chapter ends by listing several important drivers for new and enhanced broadband traffic that are important in traffic forecasting models.

Abstract—The existence of telecommunication lines in the nearby should be considered with the design of overhead transmission line. Due to the permanent load on power lines, induced electromotive force, noise and interference voltage occur in telecommunications lines. For this reason, these impacts must be carefully investigated in order to implement adequate protection measures. This paper presents an analysis of the impact of power lines on telecommunications lines, using the example of a report that considered the impact of the 2x400 kV power line Transformer Station Bajina Basta – border of Bosnia and Herzegovina/ border of Montenegro on telecommunication lines. The analysis has been done in accordance with JUS N.C0.101 and JUS N.C0.102 standards. In order to simplify calculations, TeleCAD-GIS software package was used in the analysis. At the end of the paper, solutions that can reduce the effect of power lines on telecommunications lines will be discussed.

Computational Fluid Dynamics (CFD) is widely used in the telecommunication industry to validate experimental data and obtain both qualitative and quantitative results during product development. A typical outdoor telecommunications cabinet requires the modeling of a large number of components in order to perform the required air flow and thermal design. Among these components, the heat exchanger is the most critical to thermal performance. The cabinet heat exchanger and other thermal components make up a complex thermal system. This thermal system must be characterized and optimized in a short time frame to support time-to-market requirements. CFD techniques allow for completing system thermal optimization long before product test data can be available. However, the computational model of the complex thermal system leads to a large mesh count and corresponding lengthy computational times. The objective of this paper is to present an overview of techniques to minimize the computational time for complex designs such as a heat exchanger used in telecommunication cabinets. The discussion herein presents the concepts which lead to developing a compact model of the heat exchanger, reducing the mesh count and thereby the computation time, without compromising the acceptability of the results. The model can be further simplified by identifying the components significantly affecting the physics of the problem and eliminating components that will not adversely affect either the fluid mechanics or heat transfer. This will further reduce the mesh density. Compact modeling, selective meshing, and replacing sub-components with simplified equivalent models all help reduce the overall model size. The model thus developed is compared to a benchmark case without the compact model. Given that the validity of compact models is not generalized, it is expected that this methodology can address this particular class of problems in telecommunications systems. The CFD code FLOTHERM™ by Flomerics is used to carry out the analysis.

Construction safety practices is a significant aspect in the construction industry, as construction workers cannot operate in an accident free environment without proper adherence to safety guidelines. The construction and maintenance of telecommunication masts and towers can pose serious accident threat to workers on site, hence the need to adopt the current safety practices in the sector. This study outlined the current safety practices observed by workers in the construction of telecommunication masts and towers. The study adopted a quantitative research approach and data collected from the participants involved in the construction telecommunication masts and towers in Nigeria. Information gathered was analysed using the mean item score (MIS), standard deviation (SD) and exploratory factor analysis (EFA). The findings showcased the current safety practices of telecommunication masts and towers in the Nigeria telecommunication industry to be; personal protective equipment (PPE), fire extinguisher, safety inspection, authorized entry to construction sites is prohibited, safety policy, safety education and training programs. These were seen to have a direct impact on the safety practices currently observed in the construction of telecommunications mast and towers in the Nigerian telecommunication industry. Non adherence to safety practices can hinder the welfare of the workers and economic growth of the country. Therefore, it is imperative for the telecommunication industry in Nigeria to adopt more ways of managing safety in the industry so as to improve the safety and welfare of construction workers and prevent negative economic infractions they may arise from accidents on sight. The government should adopt measures to ensure the current safety practices are enforced among all construction stakeholders who are involved in the construction of telecommunication masts and towers to prevent accidents from happening at construction sites.

Atmospheric turbulence is one of the limiting phenomena in interesting applications and fields such of optical telecommunications and Observational Astronomy. Both Telecommunication and Aerospace Engineering students may encounter those applications in their professional careers, thus, there is the necessity to introduce this phenomenon and its impact on those fields at the academic formation stage. In order to teach students of the principles and effects of the atmospheric turbulence in optical propagation, and to illustrate how to solve these problems, two different applications written in MATLAB© were developed. In this communication both applications and the theoretical background are presented, and the designed activity for Telecommunication Engineers is shown. Results obtained by students and their experience performing the activity are also presented.

The in-fiber Bragg grating is one of the most important developments in fiber telecommunications in this decade. Fiber Bragg gratings have been demonstrated that have reflectivity ranging from zero to almost one. Simple gratings have been demonstrated that have bandwidths ranging from a few GHz to many nanometers. Fiber gratings have found application in continuous wave and mode locked lasers, fiber dispersion compensation, pulse compression, fixed and tunable optical filters, add-drop filters and as demultiplexing elements. This paper will review telecommunication devices that have been realized with this key technology.
